Abstract

A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

First claim

What is claimed is:

1. A method for forming a double-sided loop strap, the method comprising:
receiving a continuous longitudinal strip of loop material comprising a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges;
folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself; and
securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap,
wherein the bonding forms discrete bonded regions of the base surrounded by unbonded area, the bonded regions including a row of the bonded regions extending along and overlapping at least one of the folded edges, and a pattern of bonded regions surrounded by engageable loops on either side of the strap.

2. The method of claim 1 , wherein folding each of the longitudinal edges comprises folding the edges sufficiently inward to meet on one side of the strap.

3. The method of claim 1 , wherein the row of bonded regions forms a seam along the longitudinal edges.

4. The method of claim 1 , wherein the bonded regions of the row of bonded regions are shaped to form visually recognizable graphics.

5. The method of claim 1 , wherein a density of the pattern of bonded regions varies widthwise and/or lengthwise along the strap.

6. The method of claim 5 , wherein the density of the pattern of bonded regions gradually increases from a center area of the strap in an outboard direction.

7. The method of claim 1 , wherein permanently bonding comprises heat staking overlapped areas of the base.
